6.2 h2000 MAIN PROCESSOR
The main processor contains two circuit boards: the wind
board and the depth board. The depth board is responsible
for boat speed, sea temperature and depth measurement. The
wind board is the main computer responsible for wind
functions and also drives the analogue meters. It has special
inputs for the mast head unit, Halcyon compass, air
temperature, battery voltage and four linear inputs which
can be connected to a variety of other sensors, see Chapter 4
- Installation Information.
6.2.1 Mast Head Unit
If there appears to be a problem with wind speed or wind
angle first check the cable connections at the main processor
and at the mast base junction box. The easiest way to test
the mast head unit cable is by substituting a spare cable. If
the cable is damaged in the mast the cause of the damage
should be ascertained and the mast re-rigged or new conduit
installed before replacing the cable. The mast head unit
should always be removed before the mast is un-stepped to
avoid damage. It should be stored in its original packing box
with the vane and cups removed.
Note
• The mast head unit's bearings should not be oiled as they
are of a sealed pre-lubricated type and additional oil may
cause chemical breakdown of the existing lubricant.
6.3 DEPTH SOUNDER
Fault finding on the depth sounder is often difficult as depth
sounder performance is dependent on many factors:
transducer type and installation, boat speed, electrical noise,
sea state, sea bed conditions, air and plankton in the water.
Indications of problems with the depth sounder normally
manifest themselves in one of three ways: display shows
